[目的]研究油菜施用氮、磷、钾肥的产量效应、经济效应及肥料的利用效率情况,为油菜高产提供依据.[方法]利用"3414"田间肥效试验,研究氮、磷、钾肥对油菜产量及经济效益的影响,分析肥料的利用效率.[结果]合理施用氮、磷、钾肥能够产生显著的增产、增收效果,油菜籽增产量最高分别达1 785、532 和 212 kg/hm~2,相对应的施肥纯增收入为5 443、1 468 和 35 元/hm2.除钾肥的农学利用率外,氮肥和磷肥的农学利用率及氮、磷、钾肥的偏生产力均随着肥料用量的增加逐渐下降. [结论]不能盲目加大肥料用量,要氮、磷、钾肥合理配施,同时加强土壤培肥也是至关重要的.

[Objective] The research aimed to study the effect of nitrogen (N),phosphorus (P) and potassium (K) fertilization and the fertilizer use efficiency of rapeseed and provide the basis for the high yield of rapeseed.[Method] The influence of the application amount of N,P and K fertilizer on rapeseed yield and profit were studied by the "3414" fertilizer experiment.[Result] The results showed that the highest increment of N,P and K were 1 785,532 and 212 kg/hm2,and the net income of N,P and K were enhanced 5 443,1 468 and 35 Yuan/hm~2,respectively.Except AE (agronomic efficiency) of K fertilizer,AE of N and P fertilizer and PFP (partial factor productivity) of N,P and K fertilizer on rapeseed had negative relationship with application rate of fertilizer.[Conclusion] The combination of N,P and K fertilization and soil fertility was important in rapeseed production.
